Ciara and Russell Wilson celebrate 1st anniversary in Mexico

The two wed last July in England.

"Mommy put a cool sign up in the sky," Wilson tells 3-year-old Future, Ciara's son from a previous relationship.

The couple also welcomed their first child together, a daughter named Sienna Princess Wilson, in April.

Their weekend vacation also included relaxing in a luxury suite.

Ciara showed off the romantic set-up by posting a picture to Instagram Sunday.

"I tried to plan things for the day, but he wouldn't let me," she wrote in the caption. "'Twas A Perfect Day. The simple things are the sweetest."

In his own anniversary message, Wilson, 27, posted a sweet video of the two from their wedding, held in a castle in England, last July.

"1 year has been amazing ... forever is even better," the video read.

Ciara, whose last name is Harris, and Wilson wed in July 2016, after a nearly four-month engagement. They were first linked in 2015 and made headlines after they disclosed they would abstain from sex until marriage.

It was the first marriage for Ciara and the second marriage for Wilson, whose first marriage, to his high school sweetheart, ended in 2014.
